NewTrend · IP67 waterproof LED power supply
Product overview
The SMV-150 is a 150 W nominal constant-voltage switching power supply with a glue-sealed aluminium housing. It accepts AC 180–264 V, 50/60 Hz and supplies a fixed DC output selected by model: SMV-150-12 for 12 V or SMV-150-24 for 24 V. Two DC lead pairs provide connection points for the selected output voltage; they are not separate 12 V and 24 V outputs on one unit.
The unit is designed for compatible LED lighting, signs, CCTV and low-voltage control equipment. Product photographs show the SMV-150-24, marked 24 V DC, 6.5 A and 150 W.

Sealed construction and stable output
The aluminium shell is filled and sealed to protect the electronics from dust and moisture. The case dissipates heat by natural air convection. The 150 W rating applies to the complete power supply, shared across its output connections. Keep the cooling surfaces clear and provide ventilation around the driver.
Protection and control
The integrated control electronics support stable constant-voltage operation. Short-circuit, overload and overvoltage protection use self-recovery. The operating-temperature range is −40°C to +65°C. Remove the fault before restoring the connected equipment and avoid touching the case when it is hot.
Input and output wiring
Connect the brown input conductor to live (L), blue to neutral (N), and yellow/green to protective earth (PE). Both DC output lead pairs use red for positive (+) and black for negative (−). Match the connected load to the selected output voltage, observe polarity, and isolate the AC supply before wiring. The combined load must remain within the unit’s total rating.
Dimensions and mounting
The dimension lines show a 240 mm overall length, 69 mm case width, 43 mm height and 216 mm mounting-hole spacing. Leads are marked 270 ±20 mm long. Use the mounting brackets and leave room for the leads to bend without strain. Keep external joints protected against moisture.
Typical applications
- Compatible 12 V or 24 V LED strips, signs and outdoor lighting.
- CCTV cameras and low-voltage security equipment.
- Compatible PLC and control-panel auxiliary loads.
